E25
Unsaturated steam
during sterilisation.
Fault during the
sterilisation phase,
probably due to a leak
during a vacuum
phase.
Allow the steriliser to cool and then
perform a vacuum test. If this is successful,
perform a sterilisation cycle with a small
load in the boiler (just one tray). If the
problem persists contact the assistance
service.
E26
Cannot reach the
cycle vacuum
threshold.
Hydraulic leak during
the vacuum phase or
overloading.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E27
Cannot reach the
cycle pressure
threshold.
Fault in the steam
generation system or
hydraulic leak or
overloading.
Perform a sterilisation cycle with a small
load in the boiler (just one tray). If the
problem persists contact the assistance
service.
E28
Sharp pressure
variation.
Excessive heating of
the steam or fault in
the pressure sensor.
Allow the steriliser to cool and then
perform a sterilisation cycle with a small
load in the boiler (just one tray). If the
problem persists contact the assistance
service.
E29
Cannot depressurise
the boiler.
Hydraulic circuit
obstructed or
electrovalve blocked.
Switch off the steriliser, allow to cool for a
few hours and then check the drain filter at
the front of the boiler. If the problem
persists contact the assistance service.
E30
Cannot balance
internal pressure with
external pressure.
Bacteriological filter
clogged.
Make sure the bacteriological filter at the
front of the machine is not clogged.
E31
Minimum vacuum not
reached during the
vacuum test.
Hydraulic leak during
vacuum phase.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E32
Maximum vacuum not
reached during the
vacuum test.
Hydraulic leak during
vacuum phase.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E33
Leak during the
balancing phase of
the vacuum test.
Hydraulic leak from a
boiler gasket.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E34
Leak during the
maintenance phase
of the vacuum test.
Hydraulic leak from a
boiler gasket.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E35
Anomalous
temperature during
the vacuum test.
Problem in the heating
system.
Allow the steriliser to cool and then
perform a vacuum test. If the problem
persists contact the assistance service.
E41
Steam generator
temperature sensor
faulty.
Fault in the sensitive
element or in the
probe connection.
Switch the steriliser off and then back on
again. If the problem persists contact the
assistance service.
E42
Upper band
temperature sensor
faulty.
Fault in the sensitive
element or in the
probe connection.
Switch the steriliser off and then back on
again. If the problem persists contact the
assistance service.
E43
Lower band
temperature sensor
faulty.
Fault in the sensitive
element or in the
probe connection.
Switch the steriliser off and then back on
again. If the problem persists contact the
assistance service.
